Brown, 24, was waived by the Bills in September after being traded to the team for a fourth-round pick, so he clearly did not live up to expectations in Buffalo. Since then, he worked out for the Patriots, Jets, and Colts, but did not receive any contract offer from those teams. Brown has yet to appear in any games this season.

In 2014, Brown played in seven games, accumulating 36 carries for 126 yards, while also having 16 receptions for 176 yards.

Johnson, 24, is a former seventh-round pick of the Jaguars back in May of last year. However, he was unfortunately waived during roster cuts a few months ago.

During his rookie season, Johnson ran for 86 yards on 29 carries (3 YPC) to go along with two rushing touchdowns and one reception for -4 yards receiving.
